Are any of the listed masters not yet raised to master (do you know when they will)? Are any listed not (yet) members (and when)? At this point I'm referring to early 708 but anything within a couple years of that can be mentioned.

Are apprentices and journeymen admitted as guild members or are they just there under their masters' memberships?

Well, there are Masters (and even Adepts) within Metamor that are not official members of any guild.

Rickkter being one - actually, following WA he would essentially be an Adept Master though he would not have anyone to administer such a test of skill to establish his rank.

Other than Morigund, there are no mages of sufficient rank to administer any tests of advancement until the local guild has Adept Grand Masters of its own.

Murikeer is another, and as the Duke's counsel for all things Magic would be de-facto liaison between the throne and any guild of magic users. Rickkter elevated him to Master rank in the autumn of 706. He refuses to be a member of any guild directly, nor confined by their bylaws. He would not attempt to control any guild or define how it functions, insofar as it does not impede or threaten the people of Metamor, its leadership, or attempt to manipulate any market in magical items for their own benefit at the detriment of trade.

In short, mage guilds would have deal with him rather than the Duke.

By 710 Kozaithy will be a Master in her own right, guildless as well.

Neither of them would establish their own guild, however, though would establish a school which would train guild members along with those without guilds. As Malger is the school's patron costs of training would be manageable - supplemented with trade in items finished during training (minor enchanted items).

We can make a list of non-guild masters too but I'm specifically asking about guild affiliated masters (and perhaps later, journeymen), whether active or keeping their distance from Kuna in the year or so since WA.
